The hoppers 14, after having been III of Fig. 1. lifted into their vertical position, as shown Fig. 4-shows the same device as that in in Figs. 1 and'3, so that the borders or flanges Fig. 3 in asomewhat modified construction. 16 are joining, form an enlargement of the enlarged at the beginning 'of the pressing The hoppers 14 have a circularshape' and pressbox. The lid 12, standing in vertical position as shown in Fig. 1, shuts this enlarged box at one side.

As soon as the lid 12 penetrates into the pressbox, as shown in dotted lines in Fig.

, 1, pushes the turnings, which are enclosed by the 2 hopp'ers '14, into the pressbox, thus subjecting the material to be pressed to a preliminary pressure before the real pressure process has begun. When the lid has been shut, the hoppers 14 can return into their horizontal position. Now the real pressure process begins in the usual way by advancing of the pressure ram 11.

Although the pressbox is generally fitted with 2 hoppers 14, it is also possible to arrange for a single hopper only, as shown in Fig. 4. This construction provides a hopper 14' on one side of the pressbox and a fixed vertical wall on the opposite side. In this case, the border or flange 16' of the hopper 14 is of suflicient length, that it joins the fixed wall 17, when the hopper is in its vertical position.

Owing to the fact, that bulky turnings, when pressed into a bundle, do not hold sufficiently together, the press, as above described, is generally combined with a device, allowing to exert a further and especially high pressure onto the bundle, thus transforming same into a briquette.

The pressboxlO of the press, represented in Figs. 5 and 6, has a lengthening 19 on one side. A pressure ram 20 moves through an opening in the opposite wall of the pressbox, this ram being. generally actuated by a hydraulic mechanism 21 and being of sufficient length so as to enter the lengthening 19. The bottom of'this lengthening 19 has an opening 22, beneath which the mould 23 of a briquetting press can be placed. At the bottom of the mould 23 a plate 25 is loosely lying on a support 24. The rotary table 26, turning around the standard 27 of a briquetting press, is fitted with several of these moulds. This briquetting press is fitted with a pressure ram 28 which can be lifted by 'means of a hydraulic cylinder 29.

A pressure ram 30 is arranged in the upper ing actuated by a hydraulic piston 32, fixed to the standard 31. As this standard 31 does not allow the arrangement of the flappable hopper 14 on-this side of the pressbox generally the construction as per Fig. 4 is adopted in this case, whereby a hopper 14 is only. provided on one side, whereas a fixed wall 17 is arranged on the side of the pressbox, opposite to the standard 31, as it is represented 1n Fig. 5.

When the turnings have been subject to a preliminary pressure by closing the lid 12, they are pressed to abundle by the advancing ram 11. As always bulky turnings are to be pressed, these do not enter the lengthwall of the lengthening 19, this ram 30 be-' ening 19, when same are compressed. As soon as the pressure ram 11 has advanced up to the chamber 19, it will be stopped, whereupon the pressure ram 20 advances. This ram exerts an additional pressure onto the pressed bundle and pushes it into the chamber 19. The bundle is hereby pressed in such a degree, that it can pass the opening 22. The pressure ram 20 will be stopped as soon as it has advanced up to the border of the opening 22. Now the pressure ram 30 is set in motion, which pushes the bundle 33 through the opening 22 into the mould 23.

The rotary table 26 can now be turned until the mould 23 with the bundle therein has reached the position above the pressure ram 28, whereupon same islifted, together with the plate 25, thus compressing the bundle into a briquette, whereby the top sill 34 of the press forms the counterplate for the mould 23, which is open at the upper end.

By further turning of the rotary table, the briquettes will then be ejected out of the mould 23 by means of a second ram, which is not represented.

The construction of the briquetting press is well known and does not form a part of this invention. My invention does however not only refer to the construction, as represented above, whereby the bundling press is arranged above the rotary table 26, turning around a vertical axle and whereby the bundle is pushed into the mould 23 from above.

The arrangement could also be made in that way, that the bundle is pushed from below into the mould of a briquetting press. Furthermore a briquetting press could be used, whereby the rotary table turns around a horizontal axle and whereby the bundling press is arranged in that way, that the bundle is pushed from thc'side into the mould of a briquetting press.

The rotary table of the briquetting press is fitted with several moulds 23. The rotary table is fitted with a bolting up device, by

means of which the rotary movement of the table can be stopped as soon as a mould 23 is standing beneath the opening 22. This locking up device is combined with the control valve of the press in that way, that the press cannot be set going, when this device is bolted up. This device does however not form a part of my invention and it is therefore not represented on the drawing. Fig. 7 represents a somewhat modified construction. Here, the pressbox 10, the pres .sure ram 11, the lateral lengthenings 19 and the pressure ram 20 have been arranged in the same way as shown in Fig. 6. The bottom .of the lengthening 19 is however not fitted pable hoppers at either sides of the 37 of the pressure ram 35 is generally somewhat larger-than the opening of the chamber 19, so that the pressure ram cannot enter this chamber. When the pressure ram 11 has advanced up to the lengthening 19-and when it has thus pressed the turnings into a bundle, this bundle will be pushed into the chamber 19 by means of the advancing ram 20. The pressure of this ram is so high, that the bundle is transformed to a briquette in the chamber 19. After this pressure process the ram 35 returns into the position as shown in dotted lines on the drawing and the ram 20 advances, so that the briquette 38 is kept outside the pressbox between the rams 20 and 35, as shown in dotted lines. 7 The briquette falls down as soon as the ram 20 is drawn back, whereupon the ram 35 is lifted anew until its head 37 reaches the opening, thus enabling the beginning of a new pressing process.
